Korea Clones Drug Sniffing Dogs

Korea has cloned seven drug sniffing dogs.

Seven dogs have been specially cloned to sniff out drugs at Korea's gateway, Incheon International Airport, where millions of overseas visitors come and go each year. Their super-sensitive schnozzles add an extra layer of security to the high-tech narcotics detection machines.

The project was led by Lee Byeongchun and his team of scientists at Seoul National University, the same team that succeeded in cloning the world's first dog back in 2005.
